The processes that control the formation, intensity and track of hurricanes are poorly understood. It has been proposed that an increase in sea surface temperatures caused by anthropogenic climate change has led to an increase in the frequency of intense tropical cyclones, but this proposal has been challenged on the basis that the instrumental record is(More)
Atlantic tropical cyclone activity, as measured by annual storm counts, reached anomalous levels over the past decade. The short nature of the historical record and potential issues with its reliability in earlier decades, however, has prompted an ongoing debate regarding the reality and significance of the recent rise. Here we place recent activity in a(More)
OBJECTIVE Our purpose was to review patients with granulosa and theca cell tumors as filed in the Emil Novak Ovarian Tumor Registry. STUDY DESIGN Our study was a descriptive, retrospective study of 454 case records. RESULTS The reviewed diagnoses were for 97 patients with granulosa cell tumors, 116 with theca cell tumors, and 97 with granulosa-theca(More)
Contemporary CPU architectures conflate virtualization and protection , imposing virtualization-related performance, programma-bility, and debuggability penalties on software requiring fine-grained protection. First observed in micro-kernel research, these problems are increasingly apparent in recent attempts to mitigate software vulnerabilities through(More)
—This paper presents a cache tracker, a hardware component to track the cache state of hundreds of caches serving processors modeled using threads on a single MIPS64 processor. This host-multithreading approach allows a single, low-cost FPGA to model large systems to allow quick and broad architectural exploration with reasonable simulation performance. The(More)
OBJECTIVE We evaluated four oral combinations of conjugated estrogens (Premarin) and medroxyprogesterone acetate in preventing endometrial hyperplasia, which can occur with conjugated estrogens alone. STUDY DESIGN This was a 1-year prospective, double-blind, randomized, multicenter study in 1724 postmenopausal women. All five groups took conjugated(More)
